Reflections off the ND filter back towards the lens will reduce the ANSI contrast slightly but will have no effect on on off contrast.
I understand; I was merely asking you why you were suggesting a ND filter over just manually clamping the iris down. The only advantage to the former I can see is that you can still use the DI, whereas with the latter, obviously, you can't.
I can't believe I'm saying this, but, w/ the 2.4 gain HCHP, the HW50ES is a little bright on a 110" screen with lamp set to 'low'. Using 'Reference' mode. Will probably be better once I get my 119" screen. Also, I was sleepy last night so maybe I was just bothered by too much light.
In 3D, though, I still wanted 'max' brightness setting for the glasses. You really just can't have too much brightness in 3D with the current round of projectors.
Is it true that the PT-AE8000U is really brighter than the Sony in 3D? Does that come at the cost of compromised color accuracy?
Also, zombie10k: will be curious to hear your thoughts about flicker on the Epson 5020. I briefly had an Epson 3010 & don't remember being bothered by flicker as much as the Sony but that is also not a fair comparison b/c the 3010 was dimmer, especially since I only had a 1.1 gain screen back then (& flicker is somewhat dependent on image brightness).
